Boston.com's Massachusetts gubernatorial debate

During a debate this afternoon, all five Democratic candidates for governor of Massachusetts said that they do not support putting accused Marathon bomber Dzhokhar Tsarnaev to death. The candidates -- Joseph Avellone, Don Berwick, Martha Coakley, Juliette Kayyem, and Steve Grossman --were all in agreement on the issue of capital punishment for Tsarnaev during a debate in the Globe Lab.
